Based on the dynamic
model of
utilization of
cultivated land resources, the model of regional differentiation of the
change in
Cultivated land and the model of spatial change in cultivated land in combination with all kinds of statistic
data, diagram and map data and data gathered from surveys on change in land use, spatio-temporal change in utilization of cultivated land in Liujiang County, Liuzhou City, Guangxi Province in the period of 1990 ~ 2000 was analyzed with a town being a research
unit. It is found that the area of cultivated land in 2000 was bigger than that in 1990 but the increase rate varied from unit to unit; in Chuanshan Town it was the highest, reaching 133.83hm2/a, but influenced by the original areas of cultivated land in 1990, the change rate was the highest with Labao Town (-2.06%) rather than Chuanshan Town; the centre of the cultivated land distribution in Liujiang County did not change much during the 10 years and moved a bit, about 0.73 km, towords southeast from that in 1990; the spatial change in cultivated land included entry and exit, which meant some farmlands were changed into gardens, forest lands or some other non-cropland meanwhile some non-farmlands were reclaimed into cultivated land, which was mainly a result of the economic development, urbanization and restructuring of agriculture.
